Blueair’s most advanced air purifier, HealthProtect provides 24/7 protection against viruses and bacteria. Each aspect of the HealthProtect 7470i air purifier is uniquely designed for maximum performance, quiet, clean air delivery and energy efficiency, with innovative smart features. Independently tested for performance as part of the AHAM Verified Program for room air cleaners, for a Clean Air Delivery Rate (CADR) of 270 for fine smoke particles, 280 for pollen particles, and 275 for dust particles. Recommended for a medium room like a master bedroom, living room, or playroom; completely filters room air about every 12.5 minutes (approx. 4.8x an hour at 418 ft ) on high. HealthProtect’s HEPASilent Ultra filtration technology filters 99.97% airborne particles, like viruses and bacteria; dust, pollen, dander, and mold, then kills 99% of the germs caught in the filter. The combination SmartFilter uses an activated carbon layer to remove gases, volatile organic compounds (VOC), chemicals, and household odors from wildfire smoke, pets, cooking, and more. HealthProtect air purifiers use SpiralAir omnidirectional airflow to quickly circulates more clean air to every corner of the room. GermShield technology proactively monitors room conditions and activates to kill germs and prevent growth on the filter, when on standby. Building on Blueair’s HEPASilent filtration technology, HEPASilent Ultra efficiently delivers 50% more clean air, 55% less energy, and 10% less noise than traditional True HEPA filtration. Meaning the HealthProtect 7470i is quieter than a whisper (22 dB) on low, less noise than a normal conversation (45 dB) on high, and uses less energy than an incandescent lightbulb (up to 47 W) even at the highest speed. Pair with the Blueair app to unlock smart features like Clean air ETA to count down the time until clean air and Welcome home function to automatically set your air purifier to standby when you leave home and back on to clean the air just before you return. RFID-equipped SmartFilters track use in real-time based on room pollution levels and actual filter loading, sending filter replacement reminders via the app to ensure timely filter replacement and continuous clean air delivery. Advanced sensors track airborne particles at three sizes (PM10, PM2.5, PM1) and display particle concentrations, volatile organic compound (VOC) levels, temperature, humidity, and filter usage on the model’s premium LCD interface. Adjust settings remotely from the app, like Auto mode, Night mode, and more with your smartphone, tablet, and Amazon Alexa (available end of October) or Google Assistant-enabled (available end of November) devices for voice control. Hidden wheels and a cord winder make it easy to move around your home. At Blueair, our Swedish heritage inspires sustainability and quality at the heart of everything we do. All Blueair purifiers are AHAM Verified for Clean Air Delivery Rate (CADR) and recommended room size, ENERGY STAR rated, and tested by the California EPA Air Resources Board (CARB) for safe ozone emissions. 24/7 protection refers to the key function of GermShield technology, activated when the unit is in standby mode.
